Nov - Science & Tech in Everyday Life
Tardigrade or water bear
found everywhere
from mountaintops
to the deep sea
and mud volcanoes
from tropical rainforests
to the Antarctic.
individual species
able to survive
extreme conditions
lethal UV radiation
such as
exposure to extreme temperatures,
extreme pressures
both high and low
air deprivation, radiation,
dehydration, and
starvation
quickly kill most other
known forms of life
survived
exposure to outer space
all five mass extinctions
less than 1 millimetre long.
prevalent
in mosses and lichens
and feed on plant cells
algae and small invertebrates
Nanotechnology for plant nutrients
Govt approved use of nanotechnology
expected to halve
use of urea
cut out dependence on import
last year
imported 9 million tonnes of urea
nano nitrogen
patent product of IFFCO
liquid form
500 ml of nano nitrogen
equivalent to 50 kg bag of urea
no subsidy
on nano nitrogen
Consumption of urea
about 35 million tonnes
70% manufactured in India
financial burden
on govt pay more than 70% subsidy
on urea to ensure
cheaper fertiliser for farmers
Tree Rings
characteristics of the rings
how old a tree is
weather conditions
during each year of that tree´s life
old trees
offer cules about
what climate in area
was like long before
Dendrochronology
(or tree-ring dating)
scientific method of dating tree rings
to exact year were formed
dendroclimatology
study of climate
and atmospheric conditions
during different periods
in histroy from wood
from 1950s to 1980s
unusually dry
TR grow wider
when soil moisture is high
reflex
more rainfall and
higher river runoff
incorporate info
about environmental conditions
Trees in the region
grow more
put on wide rings
in wet monsoon years
Dry monsoon years
TR grow less
put on narrow rings
Higher temperatures
drive more evaporation of ocean waters
in this region
water ends up
as monsoon rainfall
scientists believe
warming climate
intensify monsoon rains
in coming decades
in turn increase
seasonal flooding
